One mechanism which may be responsible for the shoreline and physical process response in the
vicinity of the Palm Beach P.E.P. reef system may be the single solid sill configuration. Physical and
numerical model tests have been performed subsequent to the Palm Beach installation to improve the
P.E.P. reef system configuration plan (Florida Institute of Technology 1995). As a result of these
tests, a new configuration has been implemented at a P.E.P. reef system installation recently
completed (i.e. September 1996) at Vero Beach, Indian River County, FL. This installation includes
both a staggered and gapped configuration (Figure 3).
